General description

Some of the tyrosine residues can be tagged with a phosphate group (phosphorylated) by protein kinases. (In its phosphorylated state, it is referred to as phosphotyrosine.). Tyrosine phosphorylation is considered as one of the key steps in signal transduction and regulation of enzymatic activity. The advent of anti-phospho-tyrosine antibodies is one of significant events in signal transduction research. Before the availability of anti-phosphotyrosine antibodies, tyrosyl phospyhorylation of proteins and enzymes was investigated through hazardous and time-consuming radioactive experiments. Anti-phosphotyrosine antibodies are commonly used in western blots after the targeted proteins have been immunoprecipitated to measure the tyrosyl phosphorylation of the proteins. Anti-phosphotyrosine antibodies are also directly used on cell lysate to examine the overall change of tyrosine phosphorylation level in reponse to various treatments.

Immunogen

Produced from CHO cells expressing the 4G10 antibody heavy and light chain cDNAs. Heavy chain C-terminus has a hexa-histidine tag for purification and immobilization via Nickel affinity matrices.

Application

Anti-Phosphotyrosine Antibody, clone 4G10 is a recombinant antibody that detects tyrosine phosphorylated proteins in all species. This unique recombinant antibody is validated for use in IC, IH, IP, WB and is published in peer review journals.

Quality

routinely evaluated by immunoblot on a modified RIPA lysate from EGF-treated human A431 carcinoma cells
